CHRISTINE DE PISAN, krḗ'stḗn' de pḗ'zäN' (1363-1431). A French writer. She wrote some controversial and historical prose, and considerable didactic verse, such as Lechemin de longue estude and the Poème de lapucelle. These works serve the historian as valuable pictures of the state of society in that day. There is an edition of her Œuvrespoétiques by Roy (1887-92). For her biography, consult Robineau (Paris, 1883).
